Description Oliver Schramm 2025-12-16 14:22:36 UTC 
Application: kdeconnectd (25.12.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.21.0
Operating System: Linux 6.17.11-300.fc43.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 43 (KDE Plasma Desktop Edition)"
DrKonqi: 6.5.4 [CoredumpBackend]

-- Information about the crash:
I've just setup a new bluetooth mouse and keyboard device (Logitech MX Mechanical Mini for Mac, don’t ask why for Mac, hah) and right after setup and trying out a few of the function keys, KDE Connect crashed multiple times.
KDE Connect has the bluetooth and wifi backend enabled and is paired with my Android phone. I don’t know if there was a bluetooth connection between my phone and my PC but there was a wifi connection available and both seemed to be connected via that.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
